get nth array row number php

Suppose you have the following array values assigned to a variable,

$erz = Array ( 
  [0] => stdClass Object ( [id] => 43 [gt] => 112.5 ) 
  [1] => stdClass Object ( [id] => 47 [gt] => 46 ) 
  [2] => stdClass Object ( [id] => 48 [gt] => 23.75 )
  [3] => stdClass Object ( [id] => 49 [gt] => 12.5 ) 
)

I need to be able to get the array index number given the id. So for instance I want to get 2 given id 48, or get 3 given id 49, etc. Is there a php command able to do this?

I dont think there is but its easy to set up your own function..

function findArrayIndex($arr, $searchId) {

    $arrLen = count($arr);
    for($i=0; $i < $arrLen; $i++) {
       if($arr[$i][id] == $searchId) return $i;
    }

    return -1;

}

No, there is no such funcion. There is an array_search() actually, but you can't use it with objects. For example, here has been asked a simmilar question: PHP - find entry by object property from a array of objects

So you have to make your own loop:

$result = null;
$givenID = 43;
foreach ($erz as $key => $element)
{
    if ($element->id == $givenID)
        $result = $key;
}
